FWIW, that worked like a charm! Of course my ship contacts have them too, but I happily ignore the exact orientation of the tails on the contacts and just use the text direction (NNE, etc.) to do my plotting to avoid having too much info.
Removing the colors are easier said then done -- I thought I'd go into the mod and see 3 different files for friend, foe and neutral, but it's apparently more complicated than that?

For now, I'm just trying to enjoy my psychic navigator.
